Abstract

A current resonance power supply circuit resonates the primary winding L61 of the switching transformer 64 and the current resonance capacitor C2I by turning on and off the switching elements 61 and 62 and obtains high frequency output from the secondary winding L62 of the switching transformer 64 according to such resonance. With a capacitor whose capacity increases as the operation frequency of the switching elements 61 and 62 decreases used as the capacitor C2I above, the out-of-resonance phenomenon hardly occurs upon a sharp drop of the AC power voltage or a quick increase of the load.
